"You monsters should not even try your tricks on me.
This humble monk explain to you the reasons.
The White Dragon Horse is headed west,
Carrying me, named Tang Sanzang, and three disciples.
We're on a pilgrimage to West Heaven, to retrieve Holy Sutras,
Not an easy journey, I telll you, measured tens of thousand miles.
On the way we've seen it all, demons disguised as beauties,
Countless traps and ruses.
All that won't stop me and my disciples going west
As my mind is set on the mission, irremovable,
Even if mountains collapse and all seas go empty."
The episode is based on stories from the Chinese classical novel Journey to the West. Tang Sanzang the Buddhist monk travels to the West to bring holy books back to China. Demons and evil spirits all try to capture him, believing that eating the monk will make one immortal. Some women also attempt to take the monk as their husband. All the attempts fail because the monk, vulnerable physically as he is, has a hard core inside. That, and the protection by the three disciples - Monkey, Piggy and Sandy, who all possess supernatural powers.
The story is about trials and redemption. Monkey, Piggy and Sandy, for example, all have their dark pasts; by going on the pilgrimage they try to redeem themselves. The White Dragon Horse, mentioned here in the song, used to be the son of a dragon lord that rules over the sea. He committed a foul and was condemned to work as a horse to pay for his mistake.
The singer is Jia Huaiyin, based in the city of Tianjin. The tune is not from any real Peking opera; it's a piece done in a variety show. It's funny because much of it was converted from a song in a cartoon movie that is well known to Chinese kids. The White Dragon Horse carrying the monk and his three disciples - that's just a jest.
